My ts 75 hasn't been cutting correctly. What I mean is this. I adjusted the saw as suggested in the tutorial on the Festool USA site. I then replaced the splinter guard on most of my tracks. I then cut them. But, when I use them, the edge guard has little notches put into it. Those notches is at the point where I plunge the saw. I also noticed that in the cuts where I plunge out of, there is a little concave subtraction of material. I spent a few days trying to tune it up, but I'm confused as what should be base line for adjustments of the saw. In the tutorial, a point was made not to plunge in or out of a cut, but what if I'm tring trying not cut all the way through? I love this saw, but I'm at the point where I wanna throw it off the roof!
